ADV.
Figure 4
4.4 I NSERTING THE BATTERY AND CONNECTING THE SWITCH
With the ADV in vertica position (see fig. 3), repeat the battery extraction procedure in
reverse order, being carefu to assemb e a parts in the correct order, meaning:
1. Connect the red connector (15) on the ower battery (14a) to the red engine
connector.
2. Insert the ower battery (14a) on the rod (13) unti it fu y rests on the bushings.
Make sure the wire does not interfere with the battery support. If so, remove the
battery and rearrange it.
3. Insert the two white distancers (60) (fig.
4. Insert the switch (61) matching up the re evant red and grey connectors. As soon
as it is inserted, the two green LEDs on the cover start to b ink. From this

4.6.
4.5 PMS (P ACK M ANAGEMENT S YSTEM ) “S WITCH ”
OPERATIONS
Figure 5
The PMS (fig. 5) is required to use two batteries without para e connections thus it can
dep ete the two batteries independent y, a ternating oad use.
When the batteries are correct y connected, the two green eds remain on for as ong as
battery power remains over the set va ue. Shou d power drop under this eve , the PMS
bypasses the battery with ow vo tage.
When the PMS bypasses the battery the re evant ed turns off. The two eds are ocated
on the side of the concerned connector. If the ed near the grey connector turns off, the
upper battery is dep eted. If the ed near the red connector turns off, the ower battery is
dep eted.
Batteries are switched every 5 seconds. This means that the two batteries are used
a ternate y for 5 seconds each.
If power is interrupted for severa seconds during ADV use, this means that one of the
two batteries was bypassed and the ADV is running on a sing e battery.
4.6 C LOSING THE BATTERY COMPARTMENT
Stand the prope er protection on a eve surface. Carefu y check that the ock O-ring
(19), (see fig. 6) is proper y seated and that it is c ean and suitab y greased with si icone

A ways make sure the switch (6) is in the off position, submerge the ADV under water
and make sure nothing is caught between the prope er b ades. If something is found
between the prope er b ades, remove the ADV from the water and free the prope er
b ades of the foreign object. Be extremely carefully since using hands r ther parts
f the b dy between the pr peller blades is p tentially hazard us, even if a safety
clutch is installed between the pr peller and engine. F r this reas n, av id
intr ducing y ur hands in the pr peller area and, if necessary f r cleaning
purp ses r t rem ve f reign bjects, use r stick r ther suitable t l.

easy to see in both immersion and emersion, which automatica y show the state of the
battery vo tage.
This gauge is not a safety system for p an your dive, it show the vo tage of the battery
pack, but the rea y time to run depends from many factor.
7 ADV DIVING SETTINGS
The ADV shou d have NEUTRAL buoyancy and be practically horizontal meaning it
shou d not sink but remain stab e at the desired depth. The vehic e is supp ied neutra y
buoyant or s ight y f oat in fresh water. Additiona weights (23), are provided to
compensate for differences between use in fresh or sa t water (see fig. 7) consisting in a
stain ess stee ci inders that shou d be inc uded or removed according to whether the
ADV is used in fresh water (NOT USED) or seawater (USED).

7.2 S ETTINGS AND TRIM ADJUSTMENTS
According to sa inity or water temperature, you may need to adjust the f oat or trim
settings (trim is the ADV ongitudina axis inc ination).
As for f oating, the ADV is produced to s ight y f oat in both fresh water (without using
the ba ast 23) and sa t water (using the ba ast 23).
As for trim, you can change factory settings by moving the battery a ong the rods (13)
(see fig.3). Remove the battery, oosen the nuts (21) with a 4 mm A en key, unscrew or
screw in the ring nuts screwing it in, the ADV tends to position itse f with the rear
sinking, unscrewing it causes the opposite. The two ring nuts must be positioned on the
rods (13) at the same distance. Screw in the nuts (21) without perforating, rep ace the
batteries and try the ADV in the water. Repeat the operation if needed unti the desired
settings are reached.

8.2 T RAINING
The ADV may be used by any diver but it is assumed that whoever is effecting the dive
has obtained the necessary certification issued by qua ified certification agencies. At
any rate, use f the ADV implies that the user has underg ne specific training that
permits him to use the vehic e safe y and to fu y appreciate its potentia . Do not forget
that the greatest danger is constituted by the underwater environment being exp ored.
8.3 E QUIPMENT CONFIGURATION AND RIDING POSITION
SUEX S.r.l. diving vehic es are TOW BEHIND type (as opposed to a “ride-on-top” which
must be stradd ed) and ideally the diver shou d be towed behind the ADV.
READ CAREFULLY! The ADV sh uld n t be impr perly b und t the diver. The
user shou d be ab e to abandon the ADV at a times and with extreme ease. The ADV
must be connected to the diver by a cord and quick-re ease carabineer. The diver
shou d a ways carry a sharp knife on dives to manage emergency situations inc uding
that of cutting the cord and abandoning the vehic e.
Pr per ways t c nnect the ADV t the diver.
The tow cord shou d be suitab e dimensioned. Use of a 4 – 6 mm cord made of non-
decaying synthetic materia , in good working order and with at east 100 kg hau age
capacity is considered correct.
The carabineer must be made of rustproof materia in good working conditions and
equipped with an easy to grasp opening device. It must a so be usab e with g oves. The
carabineer shou d be connected to the harness or “D” ring on technica ba ancing
jackets.

Figure 8
Diver position Fig. 8 i ustrates a driver in technica configuration with the ADV correct y
positioned. Other positions are admitted but considerab y reduce drive efficiency. Tow
cord ength is extreme y important for good towing efficiency. The right arm shou d
remain s ight y bent, drive the vehic e by pointing it in the direction to be fo owed but
never ho d the ADV which exerts a drive force on the tow cord.
If you prefer not to use the tow cord, both hand es must be used. This type of use does
not permit high speeds since resistance is higher with consequent arm fatigue.
The diver’s position during the dive must be more or ess horizonta (posture and
buoyancy a ways derive from correct equipment configuration and adequate training).
This ensures safety, onger running times, speed and riding comfort.
Be especia y carefu when setting out your equipment especia y as
regards: hoses, regu ators, pony bott es, pressure gauges, audib e
a arms, f ash ights and pertinent cab es, ree s, etc., making sure they
do not dang e and that they cannot come into contact with the
prope er or entang e themse ves on the bottom or on your buddy,

9 U SING THE ADV DIVING VEHICLE
Underwater diving is a potentia y dangerous activity and incorrect use of the ADV
further increases the hazards of the dive itse f.
Before use, make sure the battery is charged, that connectors are connected and that
no e ectrica parts are rusted. Check that the head cap is c osed proper y, check its
condition, especia y fo owing accidenta bumps, or accidenta scratches, and make
sure that the trigger and main switch are functioning correct y. At this point the ADV is
ready for use. After entering the water, the main switch must be switched on by rotating
it.
The main switch must be turned to running mode on y when the ADV
is in water. Rotating the prope er out of the water may be dangerous
and damage the sea of the motor shaft.
Once in the water, the prope er is activated by pu ing the trigger
incorporated on the right manoeuvring hand e towards you. Re easing the trigger wi
stop prope er rotation.
Speed can be regu ated s ow or fast, see the previous paragraph fig. 7.
10 E NTERING THE WATER WITH THE ADV
Entering the water is one of the most de icate moments in the dive.
Various factors ike the change in temperature, use of a respirator, the
weight of the equipment and other difficu ties make the addition of the
ADV an inevitab e added burden.
Before turning on or using the ADV, make sure that a the equipment
you use for the dive is correct y positioned and in good working order. On y use the
ADV after comp eting these checks. Incorrect dive preparation is high y dangerous and,

12 “P ARKING ” THE ADV UNDERWATER
When diving you may need to “park” the ADV to continue the dive with
fins on y, recovering the ADV ater. We strong y recommend you eave
the ADV far from areas with currents that cou d cause the ADV to
co ide with rock wa s, the sea bottom or boats. Vio ent co isions
cou d compromise the ADV’s hermetic sea and irreparab y damage it.
During decompression stops, be carefu the ADV does not cause uncontro ed depth
variations, turning it off and eaving it at your side.
DO NOT USE THE ADV TO MAINTAIN THE DECOMPRESSION QUOTA!
13 D ESCENT RATE
The ADV a ows you to accomp ish a fast descent rate. AVOID using it to acce erate
your descent since prob ems re ated to equa ising and psycho ogica /physica
adjustment are increased.
14 A SCENT RATE
The ADV MUST NEVER BE USED FOR VERTICAL ASCENTS. In
fact, using it in such a manner may resu t in an excessively rapid
ascent WHICH IS POTENTIALLY DANGEROUS. Hence it is better
to DEACTIVATE IT BY TURNING THE MAIN SWITCH TO THE OFF
POSITION, position it out of the way, and ascend norma y.
15 U SING THE ADV IN APNEA
Diving in apnea is high y dangerous in itse f. The use of the ADV in
apnea cou d cause serious accidents. A ways be certain and aware of
your capabi ities. Adequate training courses are essentia for your
safety.
16 D EPTH AND OPERATING ENVIRONMENTS
DO NOT EXCEED THE MAXIMUM OPERATING DEPTH!!!
The dive is a ready VERY DANGEROUS at that depth. INCORRECT USE OF THE
ADV IN SUCH ENVIRONMENTS INCREASE DIVING HAZARDS.
It is important to remember that maximum diving vehic e operating depth refers to the
ADV in prime conditions. Co isions, scratches or deformations significant y reduce this
imit.
